Electric Literature of 1552-42-7, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 1552-42-7, molcular formula is C26H29N3O2, introducing its new discovery.
A nontoxic reversible thermochromic binary system: Via pi-pi Stacking of sulfonephthaleins
The mechanisms of thermochromic materials are mostly based on Bragg reflection, surface plasmon absorption, molecular structure changes, conformational stretching or aggregation. Here, a simple class of dye-solvent binary systems with clear and reversible thermochromism around ambient temperatures is reported with an alternative mechanism. This system comprises commercially available sulfonephthaleins dissolved in liquid linear chain esters, acids or alcohols, which demonstrate colour changes at different temperatures when the solvents transition from solid to liquid states. The colour changing mechanism is based on pi-pi stacked aggregation or disaggregation of the sulfonephthalein dyes. Cell toxicity tests confirmed that the sulfonephthalein dyes are less toxic to NIH-3T3 cells than cyanidin chloride, which is the only reported nontoxic food dye affording thermochromism, while this is based on an alternative mechanism. With the choice of a nontoxic solvent, this binary system can form a nontoxic thermochromic material.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 1552-42-7 is helpful to your research. Electric Literature of 1552-42-7
